A breathing chiral molecular solid for enantioseparation via single-crystal-to-single-crystal transformation

Two chiral supramolecular porous solids derived from novel cluster-based structures of [Mn4IIIMnII] and [Mn7IIIMn3II] were synthesized. Driven by the distinct pores and host-guest interactions, they exhibited either selective gas adsorption ability for the former or the ability of enantioselective separation via reversible single-crystal-to-single-crystal transformation for the latter.
